solve problem using ratio 5:8 in a school are girls and 135 boys how many children are in the school in total.
8/8-5/8 = 3/8 Boys.
3x/8 = 135
Multiply both sides by 8/3:
X = 8/3 * 135 = 360 Children.

To solve this problem, we can start by setting up a ratio between girls and boys. According to the information given, the ratio is 5:8, which means there are 5 girls for every 8 boys.
Let's assume the number of girls in the school is '5x', where 'x' is a common factor for both the numerator and denominator in the ratio. Similarly, the number of boys in the school is '8x'.
Given that there are 135 boys, we can set up an equation: 8x = 135.
To solve for 'x', divide both sides of the equation by 8: x = 135 / 8 = 16.875.
Since we can't have fractional students, we need to round 'x' to the nearest whole number. In this case, rounding up to 17 would give us the most accurate estimate.
Now, we can find the total number of children in the school by adding the number of girls and boys:
Total number of children = Number of girls + Number of boys
= (5x) + (8x)
= 5(17) + 8(17)
= 85 + 136
= 221.
Therefore, the total number of children in the school is 221.
